Excellent carbonBy Jimon 11/13/2014

I've used many different GACs in the past - this is by far the best. Very little rinsing required - I just put it in a BRS reactor and rinse under tap water for about a minute. No fines released into tank water. Two cups last about a month on my heavily stocked 150 mixed reef.

While I can't say that I'm positive this is better then any other carbon. I like that it takes less water to rinse it.

Works Great By Martaon 10/29/2014

Almost no dust. It's simply the best carbon I've ever used. You definitely get what you pay for.

Excellent product, but not my first choice.By Charleson 10/27/2014

I used this product in my TLF reactor. It is an excellent carbon that does a much better than average job of keeping the water clean.
I suggest the white bucket test to check how well your carbon works.
I have only two reasons why this is not my first choice. The size and shape of the carbon particles.
I personally prefer the spherical beads of Sea Chem Matrix carbon. The beads are bigger and seem to have better hydrodynamic properties to me. This might be flow dependent or reactor dependent.. So please know that I would not generalize my anecdote to all tanks.
Both are excellent products, but I had trouble with this one going through filter pads. Neither one has much dust. I think that matrix carbon clumps a little less over time.
You can't go wrong with either product as long as you change it when your bucket test show yellow water.

The Best AC for your tankBy Mohamedon 10/25/2014

I use the ROX 0.8 in my BRS dual media reactor and I can’t be happier, in the past I’ve used many different activated carbon for my tank and I only liked the ROX, because the small media size I can use more media within the same given space in the reactor and thus I can add more within the reactor. Additionally it clear for me that the media do actually last longer and absorbs more and as a result I have crystal clear water that is hard to distinguish between it and between the top-up water I use.

I use this carbon in a 2 little fishies reactor and couldn't be happier. Does an excellent job keeping water clean. Less is required and in my opinion goes a much longer way than other types of carbon. I've only ever used in a reactor but I'm sure using in a bag will be quite effective.

Been using this Carbon for about a year and it's great. Works very fast - takes that yellow hue out of the water in about a day. Never had any issues with powderizing in my reactor and getting into the water column. Awesome stuff and great for the price. Worth the little extra. Thanks for a great product guys.

super quality carbon period.By Ivanon 8/26/2014

Ivan would recommend this product to a friend

this is a great high quality carbon it doesn't hold a candle to what i used to use in freshwater tanks years ago. do yourself a favor and watch the video, you will be sold. 4 stars because i believe the price could come down just a little.

I know it is a bit more expensive, but you get much longer use out of this carbon.

Good, but annoyingBy Matton 8/3/2014

Matt would recommend this product to a friend

So, I've been using Seachem Matrix Carbon in my Aquamaxx reactor for a while with no issues. i saw a good deal on the Rox at BRS, and (after all of the good word of mouth I've heard) I decided to try it.

Well, I can say it works well, at least as well as the Seachem Matrix which is a little more expensive.

BUT, it's really painful to use. Rinsing isn't even really that necessary, there's very little dust. The annoying part is that it's very small, and goes right through two filter pads. I had to add a filter sock to the output of the reactor to catch it all (a good amount had made it into my tank by now).

TL;DR - Good carbon, just be ready for it to escape into your tank and add a filter sock to your carbon reactor.

Less is MoreBy Felixon 8/1/2014

Went in with a friend to order a large supply. Really worth it as it takes a less quantity to produce crystal clear water than then bigger stuff. Since you use less, it justifies the price for a better product.
